Which instrument is a common tool for measuring the volume of liquids with marked graduations?

• A. Hand Lens
• B. pH Meter
• C. Micropipette
• D. Graduated Cylinder

Answer: (D)

Measuring liquids with marked graduations relies on a tool that provides a calibrated scale along its length. A graduated cylinder is built for this purpose: its tall, slender shape carries evenly spaced volume marks in milliliters, so you read the liquid’s amount at the bottom of the meniscus at eye level. This makes it appropriate for measuring volumes with marked graduations. The other tools don’t fit this role: a hand lens only magnifies, a pH meter measures acidity, and a micropipette is used to transfer a precise small volume rather than read an unknown volume on a scale.
